Have seen it a handful of times myself too.last year was one of them on the small rack 9pt i got.saw him chasing a doe 80 yards out and broke him off the chase by grunting.had a grunt match with him trying to find the buck he wanted to fight(me).could see his breath in the air every time he grunted.got down after the shot,stood there and 10 yards in front of me a 4pt was trailing a doe.never acknowledged me standing there in the open.
Was just one of those crazy mornings and i happened to be in stand to witness it
